About this teacher...?

well my I.T teacher is young, late 20s, and in the lessons he keeps staring at me. everyone thinks hes really hot including me. i dont know why he does it because i dont do anything to make him do it. at first i thought it was nothing and it was just because he thought i was a good student or something like that..but its the way he looks at me. and whenever he talks about relationships and stuff he looks directly at me..it makes me feel so uncomfortable. and i asked him for help and he came over, and helped me and i said thanks.. and i expected him to walk away but he just stood there. i thought he was just watching me do my work but he was staring into my eyes i really didnt know what to do so i turned around and someone walked nto the room so that made him walk away, what do you think this is about?
